The ASPICE and ISO 26262 standards focus on the refinement of the software development processes to ensure the development of high quality and safe software systems. These standards ensure that test strategies for verification start very early in the product development phases. These standards require test strategies that are consistent, ensure coverage, support exhaustive regression cycles and ensure requirements traceability with clear comprehensive reports.

TPT supports various test methods. Functional black-box tests, structural or white-box tests, module tests, integration tests: all these test methods can be easily modelled with TPT.

TPT is suitable for unit testing and integration tests, ranging from testing MiL, SiL, PiL, HiL to vehicle testing, including Back-to-Back testing. Unit testing methods supported with TPT specifically, involve testing the interface or testing based on requirements.

Besides, the “TPT Tool Qualification Package” is certified by the TÜV Saar in Germany to support all TPT users on the qualification of the TPT tool according to ISO 26262.

For given SWCs and their associated ARXML files, TPT automatically generates a test harness for functional tests. This test harness integrates a test RTE which is generated by TPT for one or more SWCs.

Designed test cases can run in many different environments for MiL testing, SiL testing, PiL testing, HiL testing, ECU testing and vehicle testing. TPT is able to execute your test cases in many well-known execution environments.

Test execution with TPT is based on a virtual machine (TPT-VM) — that is the same for all test environments supported by TPT. Several platform adapters are available to integrate the TPT-VM in different test environments.

TASMO, “Testing via Automated Search for Models”, by PikeTec generates test data by analyzing Simulink models, TargetLink models, and C-code. It finds the smallest amount of test cases to achieve the most comprehensive structural coverage (Condition Coverage, Decision Coverage) for the model or C-code. TASMO uses a unique combination of static analysis and evolutionary algorithms to fulfill its task.

Among other things, the test cases generated by TASMO can be used to run back-to-back tests and regression tests to meet the requirements of safety standards like ISO 26262.

TPT is ideally suited for testing Advanced Driver Assistance Systems (ADAS) at any test level.

For the testing of driver assistance systems, the own vehicle, the driver, road users, roads and surroundings, obstacles as well as weather and friction coefficients must be controlled in parallel and varied and combined for the test scenarios. The vehicle behaviour must be assessed in all situations. All this can be done very easily with TPT.

As with all tests, signal descriptions are necessary for module tests for driver assistance systems. Furthermore, module tests for driver assistance systems have special requirements in regard to the test software. The test software must be able to process object lists with various attributes, it must support temporal and reactive processes, and it must be able to simulate the module environment both with and without a dynamic model of the environment or rerun measured data. Additionally, a large number of scenario variants must often be tested. TPT meets all these requirements!
